查阅 可行走斜面 文档中的使用信息。

Phys Material Override

Allows you to override the PhysicalMaterial to use for simple collision on this body.

Generate Overlap Events

If true, this component will generate overlap events when it is overlapping other components (eg Begin Overlap). Both components (this and the other) must have this enabled for overlap events to occur.

@see Overlap Events @see UpdateOverlaps(), BeginComponentOverlap(), EndComponentOverlap()

属性

spacer.png

描述

Use CCD

If true Continuous Collision Detection (CCD) will be used for this component

Always Create Physics State

Indicates if we'd like to create physics state all the time (for collision and simulation). If you set this to false, it still will create physics state if collision or simulation activated. This can help performance if you'd like to avoid overhead of creating physics state when triggers

Multi Body Overlap

If true, this component will generate individual overlaps for each overlapping physics body if it is a multi-body component. When false, this component will generate only one overlap, regardless of how many physics bodies it has and how many of them are overlapping another component/body. This flag has no influence on single body components.

Check Async Scene On Move

If true, this component will look for collisions on both physic scenes during movement. Only required if the asynchronous physics scene is enabled and has geometry in it, and you wish to test for collisions with objects in that scene. @see MoveComponent()

Trace Complex On Move

If true, component sweeps with this component should trace against complex collision during movement (for example, each triangle of a mesh). If false, collision will be resolved against simple collision bounds instead. @see MoveComponent()

Return Material On Move

If true, component sweeps will return the material in their hit result. @see MoveComponent(), FHitResult

Lighting

属性

描述

Cast Shadow

Controls whether the primitive component should cast a shadow or not. This flag is ignored (no shadows will be generated) if all materials on this component have an Unlit shading model.

高级

LightingCatRefAdv.png

属性

spacer.png

描述

Affect Dynamic Indirect Lighting

Controls whether the primitive should inject light into the Light Propagation Volume. This flag is only used if CastShadow is true.

Affect Distance Field Lighting

Controls whether the primitive should affect dynamic distance field lighting methods. This flag is only used if CastShadow is true.

Cast Dynamic Shadow

Controls whether the primitive should cast shadows in the case of non precomputed shadowing. This flag is only used if CastShadow is true.

Cast Static Shadow

Whether the object should cast a static shadow from shadow casting lights. This flag is only used if CastShadow is true.

Cast Volumetric Translucent Shadow

Whether the object should cast a volumetric translucent shadow. Volumetric translucent shadows are useful for primitives with smoothly changing opacity like particles representing a volume, But have artifacts when used on highly opaque surfaces.

Self Shadow Only

When enabled, the component will only cast a shadow on itself and not other components in the world. This is especially useful for first person weapons, and forces bCastInsetShadow to be enabled.

Cast Far Shadow

When enabled, the component will be rendering into the far shadow cascades (only for directional lights).

Cast Inset Shadow

Whether this component should create a per-object shadow that gives higher effective shadow resolution. Useful for cinematic character shadowing. Assumed to be enabled if bSelfShadowOnly is enabled.

Cast Cinematic Shadow

Whether this component should cast shadows from lights that have bCastShadowsFromCinematicObjectsOnly enabled. This is useful for characters in a cinematic with special cinematic lights, where the cost of shadowmap rendering of the environment is undesired.

Cast Hidden Shadow

If true, the primitive will cast shadows even if bHidden is true. Controls whether the primitive should cast shadows when hidden. This flag is only used if CastShadow is true.

Cast Shadow as Two Sided

Whether this primitive should cast dynamic shadows as if it were a two sided material.

Light as if Static

Whether to light this primitive as if it were static, including generating lightmaps. This only has an effect for component types that can bake lighting, like static mesh components. This is useful for moving meshes that don't change significantly.

Light Attachments as Group

Whether to light this component and any attachments as a group. This only has effect on the root component of an attachment tree. When enabled, attached component shadowing settings like bCastInsetShadow, bCastVolumetricTranslucentShadow, etc, will be ignored. This is useful for improving performance when multiple movable components are attached together.

Indirect Lighting Cache Quality

Quality of indirect lighting for Movable primitives. This has a large effect on Indirect Lighting Cache update time.

Single Sample Shadow From Stationary Lights

Whether the whole component should be shadowed as one from stationary lights, which makes shadow receiving much cheaper. When enabled shadowing data comes from the volume lighting samples precomputed by [API:Lightmass] , which are very sparse. This is currently only used on stationary directional lights.

Lighting Channels

Channels that this component should be in. Lights with matching channels will affect the component. These channels only apply to opaque materials, direct lighting, and dynamic lighting and shadowing.

Rendering

属性

描述

Visible

Whether to completely draw the primitive; if false, the primitive is not drawn, does not cast a shadow.

Hidden in Game

Whether to hide the primitive in game, if the primitive is Visible.

描述

Texture Streaming

属性

描述

Force Mip Streaming

If true, forces mips for textures used by this component to be resident when this component's level is loaded.

LOD

属性

spacer.png

描述

Min Draw Distance

The minimum distance at which the primitive should be rendered, measured in world space units from the center of the primitive's bounding sphere to the camera position.

Desired Max Draw Distance

Max draw distance exposed to LDs. The real max draw distance is the min (disregarding 0) of this and volumes affecting this object.

Current Max Draw Distance

The distance to cull this primitive at. A CachedMaxDrawDistance of 0 indicates that the primitive should not be culled by distance.

Allow Cull Distance Volume

Whether to accept cull distance volumes to modify cached cull distance.

Detail Mode

If detail mode is >= system detail mode, primitive won't be rendered.

Render In Main Pass

If true, this component will be rendered in the main pass (z prepass, basepass, transparency)

Receives Decals

Whether the primitive receives decals.

Owner No See

If this is True, this component won't be visible when the view actor is the component's owner, directly or indirectly.

Only Owner See

If this is True, this component will only be visible when the view actor is the component's owner, directly or indirectly.

Treat As Background for Occlusion

Treat this primitive as part of the background for occlusion purposes. This can be used as an optimization to reduce the cost of rendering skyboxes, large ground planes that are part of the vista, etc.

Use As Occluder

Whether to render the primitive in the depth only pass. This should generally be true for all objects, and let the renderer make decisions about whether to render objects in the depth only pass.

Render CustomDepth Pass

If true, this component will be rendered in the CustomDepth pass (usually used for outlines)

CustomDepth Stencil Value

Optionally write this 0-255 value to the stencil buffer in CustomDepth pass (Requires project setting or r.CustomDepth == 3)

Translucency Sort Priority

位于高优先级物体后,绘制优先级较低的半透明物体。优先级相同的半透明物体将基于其边界原点从后向前进行渲染。

Lpv Bias Multiplier

Multiplier used to scale the Light Propagation Volume light injection bias, to reduce light bleeding. Set to 0 for no bias, 1 for default or higher for increased biasing (e.g. for thin geometry such as walls)

Bounds Scale

Scales the bounds of the object. This is useful when using World Position Offset to animate the vertices of the object outside of its bounds. Warning: Increasing the bounds of an object will reduce performance and shadow quality! Currently only used by StaticMeshComponent and SkeletalMeshComponent.

Use Attach Parent Bound

If true, this component uses its parents bounds when attached. This can be a significant optimization with many components attached together.
